As being a Copying Pencil, the lead is a mixture of graphite, wax, and a dye. This mixture has allowed the Noblot its famous ability to write on just about anything when the lead or marking surface gets wet.

The wood of a Noblot, although being strong enough to hold the pencil in place and being strong enough to write with and use in sharpeners, it is very brittle. It can break in shards if to much pressure is applied to them, as in a Crank-Sharpener.

This also has helped them get their reputation of easy breaking, since the wood is so brittle, the Pencil can be snapped with very little pressure.

The ferrule of a Noblot is strangely strong for such a small thing. Made of a metal, probably tin or brass, it can support constant hits, without getting dings or scratches. But, the ferrule, although different from plenty of pencils, can become loose, if during manufacturing, or by handling, the wood under it can snap and break off and thus make it loose. Corrective ways of fixing this include, gluing a piece of wood cut to the shape under the ferrule, or the best and easiest thing to do is to jam it. Paper jamming works best for a start, but eventually wears out, other ways to jam the ferrule are to use cloth and wrap it around, or the best, so far discovered, is to jam it with a folded piece of aluminum foil.
